But scientists have found that CBD doesn’t bind well with endocannabinoid receptors. Instead, CBD influences the system indirectly. This creates many benefits, which is why you’ll hear of CBD as a treatment for so many different medical conditions. And, unlike THC, it won’t make you high. When it comes to pain, we know that CBD has multiple functions. First, it influences neurotransmitters and receptors. One receptor known to be involved with pain and inflammation is called TRPV1 — also known as a vanilloid receptor. CBD binds to the TRPV1 receptor, influencing the way you perceive pain. CBD can also affect the production of neurotransmitters like serotonin and glutamate, which are related to pain sensation.


However, switching to CBD oil from a conventional medication is far from a random stab in the dark. In fact, there was a large scale (and very well-documented) survey carried out less than two years ago that looked at precisely what percentage of patients were able to “swap” their side effect-inducing meds for a 100% natural, cannabis-based therapy.
In addition to all the benefits we’ve already discussed, CBD has been proven to have antioxidant and neuroprotective effects. This means that it helps repair the damage from oxidative stress, which is believed to be a primary cause of diseases like Alzheimer’s, Parkinson’s, ALS — even heart disorders and some forms of cancer. This is a hugely beneficial effect of CBD.
Customer Service: It’s difficult to find contact information on Calm by Wellness’s website, and their email address is listed incorrectly in two places (we tried sending them an email but it was not delivered). We were, however, able to get a response through Facebook, and the company does offer free shipping and a generous 30-day return policy on all orders.

CBD shows promise in the treatment of anxiety disorders, according to a report published in the journal Neurotherapeutics in 2015. Looking at results from experimental research, clinical trials, and epidemiological studies, the report’s authors found evidence that CBD may help treat generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive-compulsive disorder, and post-traumatic stress disorder. However, the authors caution that human-based research on CBD and anxiety is fairly limited at this point.
Customers should always request third party lab results that test for potency, pesticides, residual solvents, and mycotoxins of the CBD hemp oil. If a company is reluctant to share these results with you, it should automatically be a red flag and indicate that they have something to hide. We’ve done the work and checked if these brands offer those tests to their customers. We’ve assigned a letter grade of C, B, A, or A+ based on what kind of lab results are offered to customers. All the brands on this list at least offer tests showing the levels of CBD and THC in them (with THC under the legal limits for hemp of 0.3%), but brands which go further are rated higher.
However, like we just mentioned CBD oil for pain management that has been sourced from industrial hemp grown under the farm bill is in fact legal to buy and sell. The best CBD oil brands that we cover here on this site, claim to extract their concentrates from U.S.-based industrial hemp supplies, which if true, are 100% legal since they contain negligible amounts of THC.
The vast majority of CBD oils come in bottles measuring either 15 milliliters (mL), or 0.5 ounces; or 30 mL, or 1 ounce. However, CBD concentration is more important than bottle size. Concentration refers to the ratio of hemp oil solution (measured in mL) compared to the amount of CBD cannabinoid (measured in milligrams, or mg). A 15-mL bottle may contain 100 mg of CBD, 300 mg, 500 mg, or more. The higher the mg amount, the stronger the CBD oil will be. For this reason, the ‘mg’ measurement is also referred to as the oil’s strength; i.e., 400-mg oil might be called 400-strength oil.
Moreover, scientists at the Cajal Institute showed promising results in regards to CBD and Multiple Sclerosis. They used animal models and cell cultures to find that CBD reversed inflammatory responses; within only ten days, mice that were used in the study had superior motor skills and showed progression in their condition. To date, there have been well over 20,000 published scientific articles on cannabinoids and their related effects on all sorts of medical ailments.
Anecdotal evidence from patients is becoming increasingly widespread as well. Morgan Freeman suffers from pain and he was quoted saying, “I have fibromyalgia pain in my arm and the only thing that offers any relief is marijuana.” Whoopi Goldberg also uses cannabis to treat her daily pain from glaucoma and has even launched a line of medical cannabis products geared towards women suffering from menstrual pain.

You should always speak with your doctor or health care professional before you start, stop, or change any prescribed part of your health care plan or treatment and to determine what course of therapy is right for you.
Dry Mouth: As is the case with many other hemp- and marijuana-based products, CBD oil often leads to a condition known as dry mouth (or cottonmouth). This is likely due to cannabinoids altering receptors in the lower jaw that trigger salivation. In most cases, mild discomfort and stronger-than-average thirst are the only issues associated with dry mouth.
The unflavored oil is derived from organic hemp seed oil. It is considered both vegan and gluten-free, and does not have any artificial sweeteners or preservatives. The oil contains 0.3% THC, meaning those who face the possibility of drug tests may want to avoid taking it, but this relatively small amount produces little, if any, psychoactive effect. The price per mg is $0.11, making the Spruce Lab Grade CBD Oil less expensive than average.
A good appetite is vital to a fit and healthy body, especially when recovering from an illness. There are certain illnesses which decrease the appetite to a point of preventing the body from properly healing itself. CBD oil helps stimulate appetite and can help a recovering patient eat much better and get healthier much faster. This is because CBD binds to the body’s cannabinoid receptors which play a vital role in regulating one’s feeding behavior.
CBD derived from marijuana is a different story, and the law varies from state to state. But as long as you’re using CBD oil that contains less than 0.3 percent THC, you have nothing to be concerned about anywhere in the United States. On the other hand, if you want to take your CBD on a trip outside the country, definitely look into local laws to avoid getting into awkward situations while you’re away.
I woke up seriously looking forward to my morning CBD oil fix … I mean, tonic. Truth be told, I’m an anxious person. Although I do a lot to try and calm my nerves, sometimes anxiety gets the best of me. But regardless of emotional or physical stress (I’m training for a marathon and running quite a bit!), I experienced this week, I felt a lot more in control after drinking my CBD oil tonics.  After work, I met up with a friend and felt like I could fully focus on our conversation without distractions. Could it be the CBD?
A study published in 1986 in the International Journal of Neuroscience, examined the effects of CBD oil in 5 patients with dystonic movement disorders (muscle tremors and other forms of uncontrollable movements). CBD oil’s side effects “were mild and included hypotension [low blood pressure], dry mouth, psychomotor slowing [slowed thoughts or movements], lightheadedness, and sedation,” according to the study’s authors, Paul Consroe, Reuven Sandyk and Stuart R. Snider.
And we have a long way to go before we fully understand the relationship between CBD and pain regulation. But strong anecdotal evidence, combined with multiple lab tests and even some clinical trials, have established that CBD holds a lot of promise for pain relief. Or in science-speak, CBD “represents a novel class of therapeutic agents for the treatment of chronic pain.”
